Embodiment
Following while with reference to accompanying drawing while one embodiment of the invention are described.Fig. 1 is the explanatory view of the infrared heating device that can use in the method for metal working related in one embodiment of the invention.
With reference to Fig. 1, metallic substance relatively high for intensification degree based on infrared heating engaged in advance with the relative low metallic substance of intensification degree based on infrared heating and the metallic substance (calling it as below " welding base material ") 4 of integration, heated from two sides by multiple near infrared lamp 5 of multiple near infrared lamp 3 of being configured in the top of welding base material 4 and the below that is configured in welding base material 4.Moreover welding base material 4 is placed on workpiece supporting rod 6, make not contact with near infrared lamp 3,5.
Then, an example of the welding base material adopted in the method for metal working related in one embodiment of the invention is described.(A) ~ (C) of Fig. 2 is the vertical view of the welding base material adopted in the method for metal working related in one embodiment of the invention.
With reference to Fig. 2 (A), welding base material 4 is by carrying out welding at welded joint position 9 with the relative high metallic substance 2 of intensification degree based on infrared heating by metallic substance 1 relatively low for the intensification degree based on infrared heating and being formed.Such as, by adopting Rustproof Steel Plate as metallic substance 1 and adopting hot compacting steel plate as metallic substance 2, the intensification degree of metallic substance 2 is set higher than the intensification degree of metallic substance 1.Thus, in heating process, reach the stage of quenching temperature at metallic substance 2, metallic substance 1 does not reach this quenching temperature.Welding base material 4 shown in Fig. 2 (A) is through heating process, forming process and refrigerating work procedure, and the skeleton part as the B post stiffener etc. of vehicle utilizes.
With reference to Fig. 2 (B), the welding base material 4 of rectangle is welded with Rustproof Steel Plate 8,8 at the welded joint position 9,9 at the two ends of general steel plate 7.And, be coated with reflective coating 10 at the central part of general steel plate 7.Because the infrared ray absorption rate of general steel plate 7 is higher than Rustproof Steel Plate 8, therefore, general steel plate 7 becomes based on the relatively high part of the intensification degree of infrared heating, and Rustproof Steel Plate 8 becomes based on the relatively low part of the intensification degree of infrared heating.In addition, in general steel plate 7, be coated with the part of reflective coating 10 compared with other parts, ultrared reflectivity is high, and the part being therefore coated with reflective coating 10 also becomes based on the relatively low part of the intensification degree of infrared heating.In the welding base material 4 shown in Fig. 2 (B), the part of general steel plate 7 (but, except being coated with the part of reflective coating 10) by quenching, by high strength, the part of Rustproof Steel Plate 8 and the part being coated with reflective coating 10 of general steel plate 7 are not kept plasticity by quenching.Such as, the part being coated with reflective coating 10 of general steel plate 7 easily carries out perforate processing etc.Like this, heated, be shaped, chilled welding base material 4, can be utilized as door anti-collision joist with being well suited for.
In addition, when when alternative reflective coating 10, coating easily absorbs ultrared absorbing coating, the part being coated with absorbing coating is locally heated, quenches and high strength.
Moreover, when the part of Rustproof Steel Plate 8 also needs quenching, as long as the output rating by improving infrared(ray)lamp, part two side of the part of general steel plate 7 and Rustproof Steel Plate 8 is heated to more than austenitizing temperature.
With reference to Fig. 2 (C), welding base material 4 engages special-shaped material and formed, and specifically, welded Rustproof Steel Plate 8, general steel plate 7, Rustproof Steel Plate 8, general steel plate 7 and Rustproof Steel Plate 8 successively at each welded joint position 9.Because the infrared ray absorption rate of general steel plate 7 is higher than Rustproof Steel Plate 8, therefore general steel plate 7 becomes based on the relatively high part of the intensification degree of infrared heating, and Rustproof Steel Plate 8 becomes based on the relatively low part of the intensification degree of infrared heating.In the welding base material 4 shown in Fig. 2 (C), by quenching, by high strength, the part of Rustproof Steel Plate 8 is not kept plasticity by quenching to the part of general steel plate 7.
Fig. 3 be represent by adopt in the method for metal working related in one embodiment of the invention, two kinds of metallic substance that intensification degree is different carry out the graphic representation of the result of infrared heating.With reference to Fig. 3, until general steel plate reach top temperature during (0 ~ 28 second), the intensification degree of the general steel plate represented with thick line is 32 DEG C/s, and the intensification degree of antirust coated steel sheet represented by dashed line is 23 DEG C/s, and both temperature heads that rises are about 10 DEG C.Reach the moment (heating starts the moment of latter 28 seconds) of top temperature at general steel plate, the temperature head of general steel plate and antirust coated steel sheet is 250 DEG C.In addition we know, after general heating starts during 20 ~ 40 seconds, the part of the general steel plate that intensification degree is relatively high reaches sufficient quenching temperature, and the part of the antirust coated steel sheet that intensification degree is relatively low does not reach quenching temperature.
From above-mentioned experimental result, by the welding base material of the relatively high general steel plate low antirust coated steel sheet relative to intensification degree of intensification degree and integration will be engaged, simultaneously and form after integrally carrying out infrared heating under identical condition, cool, only the part of general steel plate can be quenched, and make the part of antirust coated steel sheet not carry out quenching and maintaining rust-preventing characteristic or plasticity.That is, by cooling by warmed-up welding base material while stamping, the part that possessed by quenching strengthening can be obtained and not by the metal work of this two sides characteristic of the part with rust-preventing characteristic of quenching strengthening.
Moreover as the combination of the different metallic substance of intensification degree, steel plate is practical with the combination of the antirust coated steel sheet by gloss plating.By gloss plating, infrared light reflectance uprises, and therefore compared with not carrying out the general steel plate of gloss plating, intensification degree step-down, can prevent coming off of coating, in addition, can suppress the quenching of the part of having carried out gloss plating thus maintain plasticity.As the kind of gloss coating, there are nickel layer, zinc coating, alloyed hot-dip zinc-coated layer, hot dip alumin(i)um coating, chromium coating, tin coating, Gold plated Layer, silvered film, copper plate, various alloy layer.
In the scope of whole disclosure of the present invention (comprising each key element of each claim, each key element of each embodiment, each key element etc. of each accompanying drawing), the change and adjustment of embodiment or embodiment can be carried out further based on its basic fundamental thought.In addition, in the scope of claims of the present invention, various combination or the selection of the various open key element described in each embodiment, embodiment, each accompanying drawing can be carried out.That is, the present invention includes can complete according to the whole disclosures comprising claims, technological thought those skilled in the art various distortion, correction, this is self-evident.
